Will it have mundane skills like fishing or timbercraft like UnReal World?

It will not have timbercraft ( hmm but maybe it can be a kind of crafting to make for example longbows?? ), however it might have fishing… or fishing might be included in the "hunting" skill.

It is conversation and combat heavy, even if it has a bunch of other things too……..

In D&D there's this thing called 'Aid Another'. Basically, the character with the highest skill makes the roll, and other characters with the skill make a roll to aid, if they succeed they add a bonus to the character's roll.

Sounds interesting I guess it would kind of work like this but not exactly… it will not have a D&D like roll system….
